Tesla, Arm among market cap stock movers on Thursday

The article is a broad market-movers roundup highlighting steep declines in several mega-cap and large-cap stocks on Thursday. Tesla stands out with a 7.87% drop, while Arm falls 7.83%. The piece also notes weakness across semiconductor and memory-related names, including KLAC, SNDK, STX, WDC, and others, alongside sharp losses in multiple mid- and small-cap names. The main market implication is a risk-off tone in growth and tech-linked stocks, especially hardware and chip-exposed companies. The article does not identify a single catalyst for Tesla’s move; instead, it frames the action as part of a wider sector rotation and stock-specific volatility across the market.
